David Functional Annotation Repack -

DAVID doesn't just count genes. It uses a modified Fisher Exact p-value (EASE score). Look for terms with a p-value < 0.05 after Benjamini correction (FDR). The lower the p-value, the stronger the signal.

This is where the magic happens. The Three Outputs You Must Understand When the results appear, you will see a wall of data. Ignore the noise and focus on these three things: david functional annotation

"I have 4 genes." With DAVID: You run the list. The top cluster is "Amyloid precursor protein metabolic process" (Fold Enrichment: 45x). The second cluster is "Axon guidance" (Not significant? Maybe ignore). The third cluster is "Immune response" (Wait, microglia genes are also upregulated? That changes your hypothesis). DAVID doesn't just count genes
